4spaced depressions or notches 34;, the purpose of which will hereinafter appear.

Aspbefore mentioned, the sash of each window are made of tubular sheet metal. 35 indicates the sash ofthe lower or bottom window and 36 indicates the sash of the upper or top window (see Figs. l and 6 and 37 indicates the glass panes thereo said sash being of a thickness equal to the width of the runners 27. Each window front margin, as shown in Figs. l and 2,V

and the bottom member 39 of the top sash has an inwardly extending, bent-over lflange 42, which bridges the space between. the sash 35-3G defined by the intermediate strips 16 of the window frame 10. Said flange 42 terminates at its ends short of the planes of the outer surfaces of the side members 40 o1 the top sash as shown in Figs-e and t5. lWhen the top and bottom sash are in the closed position shown in Fig. l, the top surface of the flange 42 ot' the upper window sash is flush with the top surface of the top member 38 of the bottom window sash and said flange and top surface ot the bottom sash having coacting locking devices 43 ot any usual kind to lock said sash together in the closed position. Fixed to the intermediate strips 1G of the window sash at a point between the bottom member of the top sash and the top member of the bottom sash, are blocks all (see Figs. l and 4) which close the spaces at the ends oll the flange 42 ot the top window sash against the entrance of wind or rain, when said sash arc in. their normal closed position.

The side members 40 of each sash which, as before mentioned, are of a thickness equal to the width of the runner 27, are formed to provide outwardly facing bent-over anges 45 and spaces 46 between said flanges anda part of the outer web of said sash. When the sash are in their normal, upright position, the flanges and spaces of said sash and runners 27 interengage with each other, as shown in Fig. 5, the friction of said parts being suiiicient to hold them in the plane of each other against accidental displacement. The side members 40 of each sash are pivotally connected on their median line, at the bottom of the sash, to the bottom ends of the associated runners 27, bv means of studs 4:7. Each stud 47 also serves revaoei as a convenientvpoint of attachment for one end of the sash chain or cords 48, which are free to extend up through the top end of the runner and to pass over pulleys 49 at the top ends of the grooves 13-1/1, .the

other ends of the chains or cords being connected to sash weights (not shown) in the usual way provided therefor in the window frame. v w

50 indicates swinging levers which are -pivoted near their top ends, at predetermined points on the inner'strips 1.5, on pins 51. Said levers ,carry at their bottom end, rollers 52, which extend inwardly toward. each other, a 'short distance beyond the flanges 32 of the runner strips 27 as shown in Figs. l and 4. 5()a indicates similar but shorter levers which are pivoted near their top ends on pins 5la on the intermediate,

positions shown in Fig. l and it is desired to open-the lower wmdow sash either for the purpose of deiecting the incoming an' upwardly .into the room, or for the purpose of 'washing 'the outer surface of the window pane thereof.v The coacting locking devices 43, between the top of the bottom window sash and the bottom flange 42 of the top window sash are first unlocked. The top end of the bottom windowv sash is graspedand pulled inwardly, whereupon a l separation will occur `between the hook flanges 45 of the bottom window sash and the associated flanges 32 on the runners, the window swinging inwardly and downward about the pivot pins 47, before l'pntioned, las an axis. In this swinging moveihent, the side members 4() of the sash will enga-ge and pick up the rollers 52 of the levers 50, causing said levers to swing with the rollers which roll along the inner margins of the side members ot the sash until the limit of said opening movement is reached, which occurs when the sash and levers extend at about a right angle to each other. As the bottom end of levers 50 move inwardly, the shorter top ends move outwardly and enter and engage in the depressions 34 in the runners 27 to lock said runners against movement, under the action of theA sash cords or chains and associated weights. Thus even though the levers 50 assume som'e of the weight ot the window sash 85, when it has been swung inwardly and has thus removed its weight from the sash cords the sash weights cannot act to accidentally raise or litt the sash and runners while the sash is inits open position. Thus the incoming air/strikes the window pane and is deflected room Vand. the window pane is in convenient `without'the necessity of standing or sitting on the'A window sill and exposing'the person cleaifnhg the same to the danger of Jfalling from said sill. lt is apparent that, it' it ijs desired to have-the sash swing into a more nearly horizontal position than that shown in Fig. l, it is onlyl necessary to raise the window sash and rnnners vertically` in the `associated grooves" and then swing the sash ,inwardly about its pivotal connection with its ru ers until the sash again engages the rollersiQQthe relative positions ofthe pivot pins 471i, with reference to pivot 5l of the levers, determining the angular position into which the sash may be swung. 0f course the top ends of' the levers 50, will engage inlnotches 34 in the runners which are arranged therein to correspond to the position it is desired to open the windows.

To close or move the window sash back to its vertical position, it is only necessary to push the top member of the sash frame upwardly and outwardly when the coasting flanges on the runners and sash will frictionally hold the window sash in this vertical position, the levers 50 swinging back by gravity to their norma-l, `vertical positions.

To swingthe top window sash into the open position shown in Fig. 2, it is first necessary to raise the lower window sash and runners and thenpull down on the top window sash and runners, the flange 42 on the bottom member of the top sash being free to pass the rollers 52 on the levers 50a on the intermediate frame strips 16, by reason of said lange terminating short of the sides of the sash. Thereafter said top sash may be swung about its pivot with its runners in the same manner as described in connection with the bottom window sashr My improved window construction possesses many advantages-the sash may be swung inwardly about the'bottom ends as a pivot so that the sash may be used to de- Heet the incoming air upwardly toward the ceiling of the room, T hus ample ventilation may be provided without the disadvantage of having the incoming air blow directly into the room. They may also'be cleaned from within the room. The improved construction may be readily applied to old windowfraines, as well as to new window iframes. When `said sash are in their closed osition, shown in Fig. l, they are air tight to keep out drafts ot air and will not rattle. Thus the window is equally adapted for use in dwellings, as well as in oiice and shop buildings.

lVhile in describing my invention, I have referred to certain vdetails of mechanical construction and arrangement of parts, l do not wish to be limited thereto, except as may he pointed out inthe appended claims.
